We’re not alone; for repeated references to mobility, skim through the City’s Alternatives Analysis for the current rail project. Yes, it’s a long document, but to truly appreciate how and why a fixed guideway completely separated from surface traffic was selected as the best alternative to improve mobility for Honolulu residents, it's worth a fast read.
Mobility shows up early and often:
The document notes something obvious to residents on the ewa end of the island: Mobility has been lost thanks to increasingly severe traffic congestion.
Why HOT Lanes Wouldn’t Help
The Alternatives Analysis addresses why the Managed Lanes option (the so-called HOT lanes), despite possibly improved transit travel times for some origins, “…would increase traffic on the overall roadway system and create more delay for buses.” Continuing:
That’s what Honolulu’s fixed guideway project will do – deliver riders to their destination at a predictable time according to a time table, something cars can’t do no matter what lane they’re in.
